The temporary blockage of blood flow to the brain as a result of a thrombus is referred to as a TIA or Mini Stroke. In this instance, the body will react by quickly releasing tPA to dissolve the clot on its own. This body function results in symptoms, however does not result in any damage to brain tissue. This TIA is a warning sign from your body that an impending stroke will occur and medical help should be sought immediately. These mini warning signs happen in ischemic episodes and although ischemic and hemorrhagic are completely opposite situations, they both carry the same symptoms and inclinations.
Loss of blood flow due to artery blockage is an ischemic episode. This is referred to as ischemia and creates cell death and the loss of function in the extremities including the face.
Other conditions that can lead to the formation of blood clots include Atrial fibrillation, previous heart attack, heart valve diseases, some STDs, cardiovascular disease and Cerebrovascular disease.
Narrowing of the arteries due to plaque buildup, which leads to clots forming, is a common factor in ischemic events. Cells and other debris stick to cracks in the plaque.
The body protects itself from injury by forming clots. A clot is formed in order to stop constant bleeding. If the bleeding is not stopped a whole host of other, more serious complications can occur.
In order to dissolve a clot, the body will release an enzyme called plasmin to dissolve it. After this, phagocytes or white cells will come along and engulf the remaining debris, carrying it away.
Sudden headache, difficulty speaking and loss of balance are all signs of the loss of blood flow to the brain. These symptoms are generally short lived and incur no permanent brain damage. However, it is imperative that someone experiencing these symptoms seek the assistance of medical professionals as this is a warning that a more serious stroke is on the way. Treatment will consist of restoring fluid blood flow to the brain in order to prevent a more serious event.
Time is of the essence when dealing with stroke. Certain medications must be administered within the first three hours of the beginning of symptoms in order for them to work efficiently. This is why it is imperative that everyone know and recognize the signs and symptoms of stroke. If not treated in time, the patient can experience extensive and serious damage.
The onset of a mini stroke or TIA is sudden. There is no warning either as the TIA is already a warning of an ischemic event. In most cases, a major stroke will happen after one year of having a mini stroke. Visiting a medical professional is key in diagnosing your risk for this occurrence. Tests can be performed that will give your doctor a clear vision into the proper course of treatment for you.
